Anti-Claudin-19 Antibody

Raised in rabbit and affinity-purified by epitope-specific immunogen chromatography, this polyclonal IgG preparation from Antibodies.com targets the internal region of human Claudin-19, a tight-junction transmembrane protein. Supplied as a 50 µl liquid aliquot at 1 mg/mL in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide, the reagent is unconjugated and validated for Western blot (WB) and ELISA applications on human and rat samples. The antibody specifically detects endogenous levels of Claudin-19 and is intended for research use only, not for diagnostic or therapeutic purposes. The vial is shipped at 4 °C and should be aliquoted upon arrival and stored at -20 °C, with repeated freeze/thaw cycles avoided to preserve activity. This format is part of the Antibodies.com primary antibody range and is suitable for laboratories studying claudin-mediated barrier function, ion transport and related cell–cell adhesion pathways.
